I own a 2006 Hummer H2 Low Oil Pressure Warning And Dinging Noise. on 2006 Hummer H2

It went down to to 5 degrees. I took the truck out for fuel due to it being low. drove to the gas station gas light came on then low oil pressure and dinging noise started.

Went back home and parked the truck. I checked the oil it was perfect I've thought maybe because it was very cold. That may have started the problem. I will be having trucked towed to dealer later today. Has anyone had this problem?

And what type of repair cost could looking at?

It's possible it is only the oil pressure switch on this 6.0! The dinging noise is to alert you to look at the instruments to see what problem exist. Post the results so other will know.
